CA Senate Bill SB 1116: What It Means for LA Housing

What happened: On August 20, 2026, the California Senate amended SB 1116 (Caballero). The bill refines planning and zoning laws to speed up housing development projects and lower costs for starter homes. If enacted, changes to subdivisions and density would take effect for applications filed after January 1, 2027.

On August 20, 2026, the California Senate read and amended Senate Bill 1116, a significant piece of housing legislation designed to streamline the construction of smaller, more affordable starter homes. This bill is not yet law, but its progress signals major potential shifts for infill development in Los Angeles County.

What changed with SB 1116?

The August 20, 2026 amendments to SB 1116, detailed on the official California Legislative Information bill page, introduce several specific changes to state housing law, all aimed at making it easier and cheaper to build entry-level homes. The key modifications include:

• Physical Height Limits: Local height limits must apply to the physical height of a building, not the number of floors. This provides more design flexibility within a given building envelope.
• Setback Restrictions: The bill would prohibit cities from imposing most front or internal setbacks on qualifying projects, allowing for more efficient use of a lot.
• Density and Lot Rules: It modifies rules related to density to encourage more units and requires that ministerial approval provisions be interpreted liberally to produce the maximum number of homes possible.
• Minimum Parcel Sizes: On lots zoned for multifamily housing, SB 1116 would allow the creation of new for-sale parcels as small as 480 or 960 square feet if certain conditions are met.
• Lot-Size Averaging: When using lot-size averaging to create smaller parcels, none of the new lots can be more than 50% of the size of the original parcel.
• Refined Definitions: The definition of "net habitable square feet" is updated to exclude stairs and enclosed bicycle parking, and the definition of "vacant" is clarified to facilitate redevelopment of underused properties.

As explained by housing advocates at California YIMBY, the goal is to lower costs and speed construction of these smaller, lower‑cost starter homes.

When does it take effect?

SB 1116 is still in progress and is not yet law. Its effective dates are contingent on it passing the legislature and being signed by the Governor. The timeline below outlines the key dates based on the bill's current text.

What this means in the South Bay and on the Westside

If SB 1116 becomes law, it will have direct consequences for high-value, built-out communities across the Westside and South Bay. Cities like Manhattan Beach, Redondo Beach, Santa Monica, and Culver City are prime locations for the kind of infill projects this bill encourages.

The most significant local impact will be on land currently zoned for multifamily use. A property with an old duplex in West Torrance or a small apartment building in Venice could potentially be redeveloped into multiple fee-simple "starter homes" on lots as small as 480 square feet. This could increase the for-sale housing inventory at the lower end of the market.

For title and escrow, these projects introduce new complexity. We anticipate:

• More Complex Parcel Maps: Creating and insuring title for six or eight fee-simple parcels where one or two existed before requires meticulous review of new tract maps, legal descriptions, and CC&Rs. These maps must be approved and recorded with the Los Angeles County Registrar-Recorder/County Clerk before any lots can be sold.
• Scrutiny of Conditions: We will need to verify that any project using lot-size averaging complies with the 50% size cap, as a failure to do so could create a cloud on title for all parcels involved.
• Easement Intensity: Smaller lots mean more shared walls, driveways, and utility lines. This necessitates the creation and recording of more complex reciprocal easement agreements.

While the bill's push for ministerial approval could shorten entitlement timelines, the initial wave of projects will likely require extra diligence from all parties to ensure compliance with the new state framework.

What agents and homeowners should do now

With these changes potentially on the horizon for January 1, 2027, proactive agents and owners should take steps now.

1. Track the Bill's Final Status. Do not assume SB 1116 is law. Monitor its progress through the end of the legislative session. You can follow the bill's official status at the California Legislative Information bill page.
2. Consult Your Title Team Early. If you are working with a client on a potential infill development or a parcel with subdivision potential, bring us in now. We can help assess the title risks and opportunities under both current and potential future laws.
3. Review Local Multifamily Zoning. Identify properties in your farm area that could be affected. Parcels zoned R2, R3, or R4 in cities like El Segundo or Hermosa Beach are the primary targets for SB 1116-style projects.
4. Advise Clients on Shifting Land Values. For clients buying or selling property with redevelopment potential, explain that its value could change if SB 1116 passes. The ability to create more for-sale units could make a parcel more valuable.
5. Prepare for New Disclosures. If the bill passes, developers and sellers of these new starter homes will need to provide clear disclosures about the nature of the subdivision, reduced setbacks, and shared easements. Be ready to explain these to buyers.

Open Questions

As of August 24, 2026, several key questions about SB 1116 remain unanswered:

• Will the bill pass its final votes and be signed by the Governor before the legislative session ends?
• How will local jurisdictions like the City of Los Angeles or Torrance interpret the mandate for a "liberal interpretation" of rules to maximize housing?
• What new standards will lenders and appraisers develop for financing and valuing fee-simple homes on 480-square-foot lots?
• Will the bill's refined definitions for square footage lead to new, more efficient architectural designs for townhomes and stacked flats?

FAQ

Is SB 1116 law in California yet?

No. As of August 24, 2026, SB 1116 has been amended in the Senate but has not yet been passed by both legislative houses and signed into law by the Governor. It remains in progress.

If SB 1116 passes, when do the new rules start?

The new subdivision and development rules would apply to housing project applications that are submitted to local city or county planning departments on or after January 1, 2027.

What is a "starter home" under SB 1116?

SB 1116 doesn't strictly define "starter home" but facilitates their creation by allowing land zoned for multifamily use to be subdivided into small, for-sale parcels (as small as 480 square feet), which would support smaller, lower-cost housing types like townhomes.

How does SB 1116 change setbacks?

The bill would largely prohibit local governments from imposing front or internal setback requirements on qualifying housing projects, allowing builders to construct homes closer to property lines and use the lot space more effectively.

Will this affect my title insurance policy on a new home?

Yes, potentially. For homes built under SB 1116, the title policy will need to insure a more complex set of property rights, including very small lot boundaries and extensive shared easements for access and utilities. Careful review of the preliminary report will be critical.
